Title: Improvements in apparatus for softening toe-parts of uppers of boots and shoes
IPC: A43D11/14
Filed: 1921-03-05
Abstract: 161,163. Baynard, W. H. April 1, 1920, [Convention date]. Softening.-In an apparatus for softening the toe.ends of assembled uppers before lasting by treatment with hot moistened air, electric or other high-temperature heaters are used for heating the air prior to its mixing with the vapour and for producing vapour, the vaporizing-chamber is fed from a supply tank, and an outlet separate from the toe-receiving, aperture is provided for each treating chamber to minimize gaseous flow through the said aperture. As shown, assembled uppers rest on a vertically and horizontally adjustable tube 36, Fig. 4, with their toe ends in semicircular apertures in a front wall 22 of the apparatus between cut-away plates 70, 71, Fig. 5. Draught in a slack 27 draws air through apertures in the lower part of the front wall 22 to a chamber 88 whence it passes by apertures 91 past an elecric heater 85, around the toes of the shoes and over baffles 81 to the stack 27. At the same time water in a tank 39 is vaporized by submerged electrio heaters 57, the vapour passing between baffles 76, 77, over the toes and over the baffles 81. The water in' the tank 39 is constantly replenished from a heated tank 40, a valve 47 being adjusted by the operator on inspection of the water level visible in an elbow 51. The electric heaters comprise a central resistance, through which the current passes, surrounded by mica or like material for insulating the central member and conducting heat to an enclosing tube 57. This tube has heat radiating and conducting rings in contact with it which, in the case of the submerged heaters, are further enclosed in tubes 52. A rotary switch controls the heating-circuits, and a pilot lamp is provided in a shunt circuit for indicating the resistance in the heating-circuits.

Patent GB-308623-A (GB)
IPC: H01J9/50
Filed: 1929-03-07
Abstract: 308,623. Loewe, B. March 7, 1928, [Convention date]. Vacuum tubes.-In a valve having a cathode coated with one or more highly emissive substances, such as barium, several stocks of the substance are provided which are vaporized successively so as to form deposits on the cathode. The substances may be either pure metals or a mixture of a compound of, for example, barium, calcium or strontium with a reducing agent such as aluminium, silicon or magnesium. The receptacles may be of different radiating surfaces so that the evaporation or reaction temperature, when eddy-current heating is employed, is reached at different periods. In the arrangement shown, the three receptacles 7, 9, 10 provided are so dimensioned that the active material is situated at different distances from the anode and will evaporate successively under differing heating conditions of the anode. Heating of the receptacles may be effected by the passage of a current through leads connected to the receptacles. Alternatively, the materials are carried by plates inclined to one another, so that successive evaporation may be effected by eddy-current heating. The containers may carry different substances, such as barium, calcium and strontium, respectively, and these materials may be used as getters or to produce mixtures of emitting substances. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the valve shown in Fig. 1 (Cancelled), in which the anode 1 has a single receptacle 7 containing an emissive substance, a part only of which is evaporated when the first deposition on the cathode is made. This subject-matter does not appear in the Specification as accepted.

The ferrule may be of metal or of the material known under the Registered Trade Mark "Perspex" and the wedge may have a fluted end to increase the holding effect of the adhesive. Pressure may be applied to the handle before the adhesive is set to take up any shrinkage.

Title: Polymerisation of ethylene
IPC: C08F10/00
Filed: 1960-03-04
Abstract: A process for the polymerization of ethylene at raised temperatures and pressures of at least 15,000 p.s.i. comprises continuously passing ethylene together with a chain transfer agent which is acetone or an open chain or cyclic saturated hydrocarbon having at least 3 carbon atoms in the molecule and a mixed catalyst consisting of at least two organic peroxides or of at least one organic peroxide and free oxygen, the individual components of which catalysts have substantially different decomposition temperatures, through an elongated reaction zone of small cross-section relative to its length.  The chain transfer agent may be acetone, propane, n-butane, isobutane, a pentane, a hexane or cyclohexane.  Specified organic peroxides are benzoyl peroxide, lauroyl peroxide, caprylyl peroxide, 2,4-dichlorobenzoyl peroxide, t-butyl peroxyisobutyrate, p-chlorobenzoyl peroxide, di-t-butyl diperphthalate, t-butyl peracetate, t-butyl perbenzoate, dicumyl peroxide, t-butyl hydroperoxide, methyl ethyl ketone peroxide, di-t-butyl peroxide, p-menthane hydroperoxide, pinene hydroperoxide, cumene hydroperoxide and 2,5-dimethylhexane-2,5-dihydroperoxide.  Small proportions of nitrogen, methane, ethane and hydrogen may be present, and small amounts of solvents for the catalysts may be introduced therewith. Copolymers of ethylene with vinyl acetate, alkyl acrylates and methacrylates, e.g. methyl methacrylate, vinylidene fluoride and vinyl ethers may be prepared.  Flow pulses of sufficient frequency and magnitude to clear the reactor of obstructing accumulations of polymer, may be imposed on the flowing reaction mixture by operating a pressure release valve at the outlet or by varying the p  inlet flow conditions.  Examples describe the polymerization of ethylene in the presence of mixed catalysts comprising benzoyl peroxide and (1 and 2) di-t-butyl peroxide, (3) t-butyl perbenzoate and (4) oxygen; and (5) lauroyl peroxide and di-t-butyl peroxide.  Specifications 471,590, 816,110 and 891,903 are referred to.

Each of the valves has a boss 15. that of the valve 10 being secured to a spindle 19 which passes through the boss of valve 8 and a tubular extension 18 thereof. The spindle 19 has an enlarged bearing portion 20 and is supported in the end 21 of the casing, which is slotted at 22 to the entry of air. The other end of the casing is closed by an apertured member 23 which forms a support for the boss 15 of valve 8, and receives the hollow screwed stem 26 of a disc 27 secured to the dashboard 30 by a washer 28 and nut 29. Discs 31, 32 provided with a peripheral series of numerals or other marks and secured against endwise movement by a screw 33 are respectively secured to the spindles 19, 18 by keys 34, Fig. 3, engaging any diametrically opposite pair of recesses 35 in said spindles. The disc 27 may also have peripheral markings, but this is not essential. The nature of the connections 34, 35 enables the numbers on the discs which have to be aligned for starting to be varied. More than two valves, with their corresponding discs, and additional discs such as 27 with or without markings, may be employed with the object of confusing an unauthorized person.
